Patent GB-864324-A (GB)
Title: Coupling arrangement
IPC: H01P1/213
Filed: 1959-06-04
Abstract: 864,324. R.F. couplings. COMPAGNIE FRANCAISE THOMSON-HOUSTON. June 4, 1959 [June 4, 1958], No. 19173/59. Addition to 793,833. Class 40(7) A radio-frequency coupling arrangement for separating signals of two different frequencies received at a common input to two respective outputs comprises two lengths of transmission line or waveguide one of which connects the input to a matched impedance and the other the two outputs. The lengths are joined by two directional couplers spaced apart along them and two similar tuned filters, capable of transmitting signals of one frequency but reflecting those of the other, are placed, one in each length, midway between the couplers. The invention is of particular use in separating signals combined, for example by the coupling arrangement of the parent Specification, and passed through a rotating joint 4 in a common waveguide. The arrangement of the present invention, indicated at 5 and having an associated matched impedance 10 and output lines 8 and 9, separates the two signals and directs that of the frequency accepted by the filters to line 9 and that of the rejected frequency to line 8. To ensure that no signals of the unwanted frequency are passed by either lines 8 or 9 to the respective loads tuned filters 11 and 12 may be placed in these lines. These filters are tuned to accept the respective wanted frequencies and to reject the unwanted frequencies. Any energy reflected by them is not directed back to the input line but absorbed in the load 10. The filters may be waveguide Tee-filters; either of parallel type with the Tee arm connected into the short wall of a rectangular guide or of series type with the Tee arm connected into the broad guide face (Figs. 4a and 4b, both not shown).

Title: A control device for regulating the fuel supplied to an internal combustion engine
IPC: F02D1/00
Filed: 1960-06-02
Abstract: 887,135. Regulating. BENDIX CORPORATION. June 2, 1960 [June 24, 1959], No. 19596/60. Class 7(6). A fuel control lever 12 is controlled by a suction actuated spring-loaded piston- 30 sliding in a cylinder 24, which cylinder is movable by a lever 62 connected to a barometric capsule 52. The piston is loaded by a main spring 36 and by a subsidiary spring 34 which is only effective when the induction pipe pressure is - high. When the manifold pressure is low, the piston 30 is lifted in contact with a spring retainer 38 so that spring 34 is ineffective and the movement of the piston is opposed by spring 36. When the manifold pressure rises to a predetermined value, the piston 30 moves away from spring retainer 38 and the force of spring 34 moves the piston down to produce an increase in fuel supply. The capsule 52 may respond to atmospheric temperature as well as pressure.

Abstract: 1,060,983. Cyanoethylating lignocellulose pulps. GENERAL ELECTRIC CO. May 14, 1964 [May 27, 1963], No. 20201/64. Heading C3A. [Also in Division D2] A process for the cyanoethylation of lignocellulose pulp to obtain a fibrous product which can be made into a cyanoethylated paper having an improved dissipation factor comprises the steps of mixing 100 parts of the pulp with 200 parts of water and 5 to 25 parts of an alkali metal hydroxide (which is preferably dissolved in the water), adding 10 to 30 parts of acrylonitrile and mixing for 2 hours at 15‹ to 25‹ C., terminating the reaction by dilution with water while the pulp still retains its fibrous character, filtering off the pulp from the diluted reaction mixture, and then washing the pulp with water to eliminate excess alkali until the pulp has a neutral pH. Acid is not used when washing the pulp. The product may contain about 1À0 to 3À0% of nitrogen. The washed pulp may be made into paper by any desired paper-making process. The reaction may be carried out in a digester. It is preferably carried out at a temperature not below 15‹ C. and preferably between 18‹ and 20‹ C. The temperature may be 5-10‹ C. when the acrylonitrile is added to the mixture of pulp and alkali solution. Paper made from pulp treated according to the invention may be used as a dielectric in electrical apparatus and has a lower dissipation factor than paper made from cyanoethylated pulp which has been acid washed.

Title: Improvements relating to tape drive mechanisms

Abstract: 1,124,215. Tape drive mechanisms. FERRANTI Ltd. 2 May, 1967 [9 May, 1966], No. 20220/67. Heading G5R. [Also in Division F2] A tape drive mechanism comprises a drive member rotatably mounted on a frame, first and second drive control members mounted adjacent to and coaxial with the drive member on opposite sides of it and each having a surface arranged to be in light frictional contact with it, means for producing relative rotation between the two drive control members, and control means operable to increase the frictional contact between the drive member and one or other of two drive control members as the case may be. As shown, a hollow sleeve 34 is driven around a stationary shaft 26 by a belt and pulley 14, 16; the left-hand end of the sleeve is in the form of a boss 46, and forms with a fixed core 38, 40, 42, carrying a winding 52, part of an electromagnetic clutch. The remaining members of the clutch are a rotatable disc 28 (the " drive member ") and a cylinder 50 secured to boss 46. When winding 52 is energized, disc 28 is drawn into close contact with frictional facing members 53 on the rotating parts 46, 50, and is driven thereby. Mounted on the disc 28 is a peripheral ring 18 forming a tape-driving capstan and co-operating with a retractable pinch roller (not shown). Mounted on the opposite side of disc 18 is an electromagnetic brake similar in construction to the clutch, except that the parts 134, 146, 150 corresponding to parts 34, 46, and 50 are fixed instead of rotary. When winding 152 is energized, disc 28 is drawn to the left into close contact with frictional facing members 153 and is thus brought to rest. All the parts are normally maintained in light axial contact by a spring 156. Instead of the brake, a second clutch arranged to rotate in the same or the opposite direction may be provided. For tape with sprocket holes, projecting teeth may be formed around the capstan 18. Alternatively, the capstan may be omitted, teeth formed directly around disc 28, and a smooth supporting surface provided over which the tape may slide.

[Class 140] [Also in Group XXIII] A composite board comprises two parallel sheets of wood or plywood, between which are placed side by side prisms of cork firmly compressed one against the other parallel to the sheets, to which they are glued 'under pressure. To obtain the board, the curved and irregular-shaped natural cork is cut, perpendicularly to the surface, into strips of the required width, which are then planed parallel to the inner and outer surfaces of the bark to the desired thickness. The strips are placed side by side and pressed together without glue, to form a practically homogeneous block to which the wood or plywood sheets are glued. The prisms may alternatively be of agglomerated cork. In a modification, a sheet of asbestos-cement is substituted for one of the wood or plywood sheets, or a sheet of asbestos-cement may be placed between two layers of cork prisms, the outer sides of which layers are bounded by wood or plywood sheets. The Specification as open to inspection under Sect. 91 comprises also a board wherein the prisms of cork are replaced by sheets of agglomerated cork. This subjectmatter does not appear in the Specification as accepted.
